Answer:

$20.02

Step-by-step explanation:

Convert the percentage to a decimal.

9% = 0.09

Multiply the cost of the shirt by the decimal.

22 × 0.09 = 1.98

Now, subtract the cost of the shirt by the calculated number.

22 - 1.98 = 20.02

The price of the shirt is $20.02.

Answer:

Step-by-step explanation:

Two events are termed to be mutually exclusive if they cannot happen at the same time. This means that the probability of occurring at the same time is zero.

A is correct.

The probability of the two events happening at the same time is zero

B is incorrect

The probability of both happening at the same is not equal to the probability of B alone

C is incorrect

The probability of the union of the two is never equal to zero since they might occur at different times

D. Is incorrect

The probability of both happening at the same time is never equal to the probability of A alone

Please help e and my sister want to go somewhere but we cant because of this

gtnhenbr [62]

Answer:

1 5/12 lb

Step-by-step explanation:

This is a subtraction problem.

He started with 4 2/3 lb and used 3 1/4 lb, so you need to subtract 3 1/4 lb from 4 2/3 lb.

Notice that the fractions do not have the same denominator, so we need a common denominator and equivalent fractions.

We start with the

subtraction below

4 2/3

- 3 1/4

---------------

The least common denominator of 3 and 4 is 12. 12/3 = 4, and 12/4 = 3, so we get equivalent fractions with the common denominator 12.

We use the LCD to get

the subtraction below

4 8/12

- 3 3/12

----------------

Now we subtract the whole numbers and the fractions.

4 8/12

- 3 3/12

----------------

1 5/12

Answer: 1 5/12 lb

The square of the sum of two consecutive natural numbers is greater than the sum of the squares of these two numbers by 112. fin

Verdich [7]

We solve the equation, ( a + a + 1 )^2 = 112 + a^2 + ( a + 1 )^2;
Then, ( 2a + 1 )^2 = 112 + a^2 + a^2 + 2a +1;
4a^2 + 4a + 1 = 113 + 2a^2 + 2a;
Finally, 2a^2 + 2a - 112 = 0;
a^2 + a - 56 = 0;
We use <span>Quadratic Formula for this Quadratic Equation;
The solutions are a1 = 7 and a2 = -8;
But a is a natural number; so, a = 7;
The natural consecutive numbers are 7 and 8.</span>
